VAPORIZING DEVICE FOR GASOLINE ENGINES.

Application filed December 13, 1921.

To all whom it may concern:

Be it known that I, CARL D. TURNER a. ing motor.

citizen of the United States, residing at ndianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in vaporizing Devices for Gasoline Engines, of which the following is a specification.

The object of my said invention is to provide a device which will serve to vaporize the gasoline at the time of starting the engine so that the starting operation may be effected promptly and with the least possible trouble, and the operation of the starting apparatus made more reliable and effective. I accomplish said object by providing a resistance coil at the entrance to the intake manifold and preferably connecting the same in the operating circuit of the starting motor so that as the starting switch is thrown to close the starting circuit a current is also passed throu h said resistance coil, and the same heate to a vaporizing temperature, with the result that the gasoline passing over said coil is vaporized and the engine started easil and instantaneously, all as will be hereina ter more fully described and claimed.

Referring to the accompanying drawings which are made a art hereof and on which similar reference 0 aracters indicate similar parts,

Figure 1 is a view showing a gasoline motor and the parts to which my invention relates illustrated in diagrammatic form,

Figure 2 a, plan view of the gasket forming a leading part of the means employed for supporting the resistance coil in position, and

Figures 3 and 4 sectional views at the joint between the carbureter and the intake manifold showing the manner of applying my device.

In said drawings, the portions marked A represent the engine, B the battery, 0 the carburetor, D the intake manifold, E the starting motor, and F the switch for controlling the current from the battery to the starting motor, all of which parts are or may be of any usual or appropriate construction and arrangement and require no special description herein except such as may be incidental to the description of my said invention.

As is common, the battery B is connected with the starting motor E by wire 10 con- Serial No. 522,151.

nected with a terminal post 11 on said start- The carbureter C and intake manifold D are joined together by means of outwardly extending abutting flanges through which clamping bolts 20 extend, the gasket being placed between them, as usual.

My invention consists in a device comprising a coil 21 of wire made of nickel chromium alloy, or material of similar resistance character, having suflicient resistance so that the passage of the current therethrough will generate the heat required to bring the coil to a temperature that will vaporize gasoline. One end of said coil 21 is connected, preferably by welding. to a metal plate 13 interposed between two plates 14 and 15 of insulating material and the other end is connected to another metal plate 16 on the outside of one of said insulating plates.

The member thus made up forms a gasket composed of alternate plates of metal and insulating material and is adapted to be inserted in the joint between the intake manifold and the carbureter in the same way, and serve the same purpose, as an ordinary gasket. When so'inserted, the heating coil 21 projects into the manifold or carburetor casing as will be noted from an inspection of Figures 3 and 4.

An car 24 extends outwardly from the central metal plate 13 of the gasket to which one end of the coil 21 is connected and an insulated conductor 22 is welded to said ear and on its other end has a terminal plate 23 adapted for connection with the terminal post 11 of the starting motor as shown. It will thus be seen that when the parts are connected up, as explained, and the switch F is closed, a circuit will be established from the battery through the wirelO and conductor 22 to the plate 13 and thence through the coil 21 to outside plate 16 and from said plate 16 through the engine and frame, the usual ground connection of the battery, to the ground.

In a two-wire starting system, two wires will be provided toform the circuit and supply the current for heating the resistance element in a similar manner, as will be readily understood by those familiar with the art.

The installation of this device requires but a'few moments and does not require the machining of any parts to which it is attached. Its operation is effected automatically through the closing of the starting motor switch and the gasoline passing over the coil, which heats instantly after the throwing of said switch to a point where it serves to vaporize said gasoline, even when the engine has been standing for a long time in cold weather, thus insuring a quick and sure start of the motor under conditions which ordinarily make the starting of the motor very difficult and uncertain.

When the starting motor switch has been opened and the current disconnected, the coil will, of course, remain in the same position. in which it serves as a means for breaking up the gasoline in its passage into the intake manifold and aids in perfecting the mixture and the carburization of the fuel, so that even when not in use as a vaporizer it serves to aid in increasing the efficiency of the motor, 'experience having demonstrated that the same motorthus equipped will give a materially greater mileage per gallon of gasoline than without such device.

In manufacturing the gasket,'the several plates are punched out by appropriate dies or machines, and are assembled under pressure so that in the operation of assembling, the hollow insulating rivets 25 in the apertures are upset sufficiently to retain the several parts firmly in assembled position.

It will be understood, of course. that many modifications in details of construction and arrangement of parts may be made without departing from the spirit of my invention, the device as illustrated being one that in actual practice has been found very desirable because of its simplicity, efficiency, and ease with which it may be attached, but it will be obvious to those skilled in the art that the details may be materially modified without in any way defeating the operation or deteriorating the efficiency of the device.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is:

1. A heating device interposed in the intake manifold of a gasoline engine and connected in the circuit with the starting n10- tor to be heated by the operating current for said starting motor.

2. A device for assisting in the vaporizat1on of gasoline in connection with internal combustion engines comprising a gasket adapted for use in the joint between the carbureter and intake manifold and composed of alternate plates of metal and insulating material, a coil of resistance material one end of which is connected to one metal plate and the other to another metal plate insulated from the first, and connections running therefrom to establish a complete circuit, substantially as set forth.

3. A gasket for intake manifolds of internal combusion engines comprising alternate layers of conducting and insulating material, and a resistance element in the central aperture of the gasket connected to two conducting layers, substantially as set forth.

4. A gasket for intake manifolds of internal combusion engines comprising alternate layers of conducting and insulating material, a resistance element in the central aperture of the gasket connected to two conducting layers, and an ear integral with and extending from one of said conducting layers for attachment of a lead wire, substantially as set forth.

5. A gasket adapted to be inserted in the bolted joint between a carburetor and an intake manifold of internal combustion engines comprising alternate layers of conducting and insulating material, a resistance element in the central aperture of the gasket connected to two conducting layers, hollow insulating rivets extending through and securing together the layers of conducting and insulating material, the hollow portions of the rivets also being adapted to re ceive the said bolts of the said joint to hold the layers in place with respect to the joint and also to insulate the bolts from the said layers, substantially as set forth.

In witness whereof, I have hereunto set my hand and seal at Indianapolis, Indiana, this 9th day of December, A. D. nineteen hundred and twenty-one.
